Quizplus · Accepted Answer

H₃PO₄ is a strong acid, so it will completely ionize in solution. The only factor affecting the pH will be the concentration of the acid. Using the equation pH = -log[H+], we can calculate the pH of the solution to be -log(7.5) = 0.63. Therefore, the correct answer is A.
